REFRIGERATOR..

SPECIFICATION forming part of Letters Patent No. 246,993, dated September'l, 1881.

Application nieu May 14, 1881. (Model.)

To all whom it may concern Be it known that I, JOHN ANGUs, of the city, count-y, and State of New York, have in- .vented an Improvement in Refrigerators, of

ber, and one or more distributing, discharging, or outlet tubes leading from said condens ing and distributing chamber to one or more provision-chambers.

.The above combination of three elements constitutes ameans of cooling and supplying air by passing itthrough the ice-chamber without its coming in Contact with theice, the condensing chamber operating to collect any sweat, drip, or Water, (should any collect in the passage,) and preventing its passage or escapeinto the provision-chamber, as I especially desire to supply cold dry air as free from moistnre as possible. The arrangement is such that a continuous descent is obtained for the air-currents on the principle that cold air descends, thereby making the supply self-actin g and perpetual; and, further, to render this effectual and keep up the supply in continuous currents, I provide, at a suitable part of the provision chamber or chambers, outlet or ventilating apertures, (dampered or not,) so that the warm air rising Within will make its escape, readily'carrying off at the same time all odors, steam, 85o., and keeping the interior dry, pure, and wholesome.

In the accompanying drawings, Figure l represents exterior in perspective 5 Fig. 2, section from sideto side Fig. 3, section from front to rear; Fig. 4, horizontal section through icechamber; Fig. 5, horizontal section through provision-chambers and water-tank. Fig 6 represents the supply-tube, condensing and distributing chamber, and two distributing or discharging tubes, all in perspective. Fig. 2 shows section of'said chamber, dischargingtubes, and Aportion of supply-tube. A section crosswise the same is shown in Fig. 3.

A represents outside walls of a refrigerator; A', the division between ice-chamber and one or more provision-chambers; A2, the division or space between the provision-chambers.

B is the cooling and supply tube '(or airduct) communicating with the Outer air, receiving supply therefrom. It has no communication between its interior and the ice chamber.

Gis the condensing, cooling, and distributing chamber, to which is attached the supplytube B in such manner that air may be supplied to interior of condensingand distributing chamber U.

It is not material at what point or through which side the tube B is connected, as it might be through the top or either side, and the tube may be of any suitable length, size, or shape,

Or bent in any direction, so long as proper de scent is obtained, and distance for cooling the air; also, the size, shape, or location of chamber C, I do not conlne, as it may be large enough to distribute for many provision-chambers or limited to only one, as requisite; and it may be of any shape desirable or most convenient, and it maybe located wherever economy and efficiency may indicate. I prefer that the ice shall rest upon the tube B, and probably upon the top ot' chamber-G, as I desire to get as much cooling e'ect as possible, the

air being cooled in both.

Out of thecondensing and distributing chamber O proceed the distributing or discharging tubes D, (one or more, as desired,) the upper ends being elevated sufficiently above the bottom of chamber (l to effectually prevent water or drip from getting into them,and thence to provision-chambers. The tubes D pass downward and enter provision chamber or chambers E E.

An outlet is provided leading from chamber C, for escape of water, and it may be carried carried therefrom in any suitable manner and to any suitable place.

be filled with non-conducting material, or left' as dead-air space. Said tank G reaches to bot- 1 tom ot' refrigerator, and is provided with faucet H and overflow-pipe I, the overliow proceeding downward from bottom ot'. tank curving upward, forming a trap to prevent intlowingaircurrents escaping tointerior ot' tank, and thence to ice-chamber, 85e.

A tube=connection, J, provides means for water to enter tank from ice-chamber B.

Theoperation is asl follows, viz: Ice beingy placed into the ice-chamber B', resting upon the tube B 'and chamber C, the covers are shut, and ice-chamber made air-tight. Soon the air within the chamber G becomes cooled, and descends through distributing-tubes D to interior of provision-chamber E, being followed up by air from supply-tube B, which draws air from outside the refrigerator, cooling it in its passage, and it is still further cooled in chamber C all the time. As the cold air enters provision chamber or chambers E it descends to the bottom, while the warm air, &c., rises and escapes throughv apertures F, and this process is con.- tinuous. All the moisture from sweat, Sac.,

Vwhich may get in the tube B is collected inY chamber C, and as the tubes D are extended above its bottom the water cannot enter'them, and as they do not come in contact with the ice there is no sweat in them, so that the aircurrent is delivered in a dry state.

The condensing-chamber C is a very important part of my invention, as Without it the sweat from tube B would enter provision-chambers, and, again, without it as a distributer separate pipes would be necessitated wherever more than one provision-chamber was required, adding greatly to the expense. While I have found by experience and practice that a break must be made between the supply-tube and the provision-chamber, (and this I accomplish by chamber 0,) of course it must be proportioned properly with regard to its supply and its discharge, and it is absolutely necessary to prevent accumulation of moisture from reachingthe provision-chamber, whether one or more are used.

The above combination-ot' supply-tube B, condensing-chamber C, and distributing-tube D (one or more) may be applied to any refrigerator wherein the ice-box is air-tight, and located sufficiently high, and wherein the arrangement of provision-chambers willv admit, the essentials being proper descent and a tight icecbamber having no communication with provision-chambers.

The provision chamber or chambers may have any amount of ventilation, and the apertures may be provided with valves or dampers;

but it is essential that there shouldrbe some outlet therefrom to keep the cold-air current in motion.

' What I claim as my invention, and desire to The'combination of the supply and cooling tube B, cooling, distributing, and drip-collectingor condensing` chamber C, and one or more air-discharging tubes, D, as and for the purn pose described and set forth.
